INA195AIDBVTG4

Current Regulation/Management Overview

The INA195AIDBVTG4 is a high-side current shunt monitor manufactured by Texas Instruments, designed for precise current sensing in power management applications. It operates with a supply voltage range of 2.7 V to 18 V and supports common-mode voltages from -6 V to 80 V. The device features an accuracy of ±3% and consumes 900 µA of operating current. It is housed in a compact SOT-23-5 surface-mount package and functions within a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• High-side current monitoring capability with wide common-mode voltage support
• Integrated precision amplifier for accurate shunt voltage measurement
• Low power consumption suitable for battery-operated systems

Current Regulation/Management Applications

• Battery protection circuits
• Overcurrent protection in industrial equipment
• Power management unit (PMU) current sensing

Current Regulation/Management Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm availability status, as some sources indicate this specific variant may be obsolete or discontinued, requiring validation of active stock or recommended alternatives before procurement planning.

Current Regulation/Management Selection Notes

Select this component when high-side sensing is required with a common-mode voltage exceeding the supply rail. Ensure the application voltage does not exceed the 80 V common-mode limit. Consider the ±3% accuracy specification against system tolerance requirements. Verify thermal performance within the specified -40°C to +125°C operating range.

Current Regulation/Management Part Context

This part belongs to the INA19x family of current shunt monitors from Texas Instruments. It shares functional similarities with the INA193 and INA195 variants but is distinguished by its specific packaging and grade. The 'G4' suffix typically denotes a lead-free, RoHS-compliant version of the standard INA195AIDBVT device.

Current Regulation/Management Replacement Considerations

Texas Instruments recommends the INA195AIDBVT as a direct substitute. Verify pinout compatibility and electrical specifications match the original design requirements before substitution.
